Registering And Defining An Embedded Event Manager Tcl Script; Displaying Embedded Event Manager Information - Cisco ME 3400 Software Configuration Manual

Displaying Embedded Event Manager Information

These examples show actions that are taken in response to an EEM event:
Switch(config-applet)# action 1.0 syslog priority critical msg "Memory exhausted; current
available memory is $_snmp_oid_val bytes"
Switch (config-applet)# action 2.0 force-switchover

Registering and Defining an Embedded Event Manager TCL Script

Beginning in privileged EXEC mode, perform this task to register a TCL script with EEM and to define
the TCL script and policy commands.

This example shows a CRON timer environment variable, which is assigned by the software, to be set to
every second minute, every hour of every day:
Switch (config)# event manager environment_cron_entry 0-59/2 0-23/1 * * 0-6
This example shows the sample EEM policy named tm_cli_cmd.tcl registered as a system
policy. The system policies are part of the Cisco IOS image. User-defined TCL scripts must
first be copied to flash memory.
Switch (config)# event manager policy tm_cli_cmd.tcl type system
